• A civic operations board needs numeric invoke rates and threshold alerts for Oracle Functions, plus separate stores for log lines and distributed traces. Which OCI service holds metrics and alarms?
• After deploying a new Oracle Function for online payments, the team wants invocation and duration charts. What must they enable first?
• Citizens report that a permitting Function sometimes fails, sometimes feels slow, and sometimes seems overwhelmed. Which metric mapping is correct?
• The Throttles chart for a city’s notifications Function lights up during a mailing spike. What does a throttled invocation mean, and what should developers do first?
• Service Metrics for ocifaas shows noise from every Function in the compartment. How should an operator isolate one permitting Function’s charts?
• A city parking-permit portal team wants a Monitoring chart that shows peak API Gateway request volume during permit renewals. Besides the metric name in the ociapigateway namespace, which two other pieces must the metric query include?
• The municipal snow-route dispatcher wants an alarm that pages on-call when permit-API latency stays high, but a single one-minute spike should not wake anyone. Which alarm design matches OCI Monitoring practice?
• When a parks recreation booking alarm fires, where should the firing message go so on-call staff get email or PagerDuty, without treating Logging as the alarm destination?
• A water-utility OKE cluster shows citizen-portal pods stuck Pending while nodes report not Ready. Which Monitoring approach matches what OCI emits automatically for the cluster and nodes?
• Citizens report slow permit lookups through API Gateway in front of an Oracle Function. Which metric pair best separates gateway overhead from time spent in the Function backend?
• A building-permit team needs application print lines from an Oracle Function, not the tenancy’s public-API trail. Which Logging kind should they enable for that Functions output?
• The library card-renewal API Gateway has no events in Logging yet. What must the developer do so the service starts writing those events?
• A city IT lead wants one IAM boundary and one search scope for all recreation-booking logs across environments. Which Logging construct is the unit that provides that management shape?
• Where does a developer enable Function Invocation Logs so default invocation records appear for functions in a municipal payments Fn application?
• After enabling invocation logs, a tax-assessment Function still shows no diagnostic lines about which parcel ID failed. What else must be true for those custom lines to appear in Logging?
• A permit-status Function prints valid JSON objects, but Logging Search cannot filter on nested fields. Which application setting change unlocks structured fields for advanced filters?
• A transit-pass microservice on OKE writes helpful errors to stdout, but Logging still shows nothing from the app. Which path correctly gets those lines into OCI Logging?
• Pods for a marina slip-reservation app will not schedule, and the team needs control-plane scheduler and API server detail—not the app’s stdout. Which log kind answers that question?
• During a festival ticket outage, operators need one Logging query that spans the API Gateway service log and the Functions invocation log group. What does OCI Logging search support?
• A citizen’s failed dog-license renewal hit API Gateway then an Oracle Function. Which field is the documented way to join gateway and function log lines for that same client call?
• The health-department Fn team wants a span tree for each immunization-appointment Function invocation. Where should those traces be sent?
• While reviewing APM for a grants portal Function, a developer confuses terminology. What is the difference between a trace and a span?
• A clerk portal Functions app has an APM domain ready, but function-level tracing toggles never appear. What enablement order does OCI require?
• After tracing is enabled for a utility-billing Function, Trace Explorer shows an outer invocation span but nothing for the Vault secret fetch inside. What does that indicate?
• Developers want a named custom span around a downstream Function call from a code-enforcement Fn. Which approach matches the official custom-span path?
• Metrics show a long duration for a zoning-variance Function, but not where time was spent. Where should the developer inspect the request’s span tree?
• A business-license Function invokes a fee-calculator Function, but Trace Explorer shows two unrelated traces. What is missing for a single tree covering both?
• On-call for a city payments stack asks three different questions. Which matching is correct?
• A refuse-collection Function starts failing for some ZIP codes. What ordered use of the three official tools matches Functions troubleshooting practice?
• During a planned deploy of the business-license API, the team still wants metrics and logs but must not page the Notifications topic. Which Monitoring action fits?
